The left side of the tongue root is thicker than the right side.
As long as there are no ulcers, swelling, or discomfort, and no difficulty swallowing, it should not affect oral health.
It is recommended to consult a dentist for further evaluation.

It is not uncommon for individuals to notice asymmetries in their bodies, including the tongue. The thickness of one side of the tongue compared to the other can be attributed to various factors, and while it may not always indicate a serious issue, it is important to consider the context and any accompanying symptoms.

In your case, if you observe that the left side of your tongue appears thicker than the right side but there are no lesions, sores, or other concerning symptoms, it may simply be a normal anatomical variation. The human body often exhibits asymmetries, and slight differences in the size or shape of body parts, including the tongue, can be completely benign.

However, there are several potential reasons for the observed thickness on one side of the tongue:
1. Muscle Hypertrophy: If you tend to chew more on one side of your mouth, the muscles on that side of the tongue may develop more, leading to a thicker appearance. This is similar to how muscles in the arms or legs can become larger with more use.

2. Injury or Trauma: If you have inadvertently bitten your tongue or experienced some form of trauma, swelling may occur, leading to a temporary increase in thickness.

3. Inflammation: Conditions such as glossitis, which is inflammation of the tongue, can cause swelling. This can be due to various reasons, including allergic reactions, infections, or irritants.

4. Geographic Tongue: This benign condition can cause patches on the tongue that may appear raised or swollen. It is usually harmless and does not require treatment.

5. Underlying Health Conditions: In rare cases, asymmetry in the tongue can be associated with certain health conditions, such as neurological disorders or systemic diseases. If you experience other symptoms, such as pain, difficulty swallowing, or changes in taste, it would be advisable to seek medical evaluation.

If the asymmetry is new, persistent, or accompanied by other symptoms, it would be prudent to consult a healthcare professional, preferably an ear, nose, and throat (ENT) specialist or a dentist. They can perform a thorough examination and determine if any further investigation is necessary.

In summary, while a thicker left side of the tongue can be normal for some individuals, it is essential to monitor for any changes or additional symptoms. If you have concerns, do not hesitate to seek medical advice for peace of mind and to rule out any underlying issues.
